| * mtd: rawnand: Support bad block markers in first, second or last pageFrieder Schrempf2019-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently supported bad block marker positions within the block are: * in first page only * in last page only * in first or second page Some ESMT NANDs are known to have been shipped by the manufacturer with bad block markers in the first or last page, instead of the first or second page. Also the datasheets for Cypress/Spansion/AMD NANDs claim that the first, second *and* last page needs to be checked. Therefore we make it possible to set NAND_BBM_FIRSTPAGE, NAND_BBM_SECONDPAGE and NAND_BBM_LASTPAGE independently in any combination. To simplify the code, the logic to evaluate the flags is moved to a a new function nand_bbm_get_next_page().

| * mtd: nand: Make flags for bad block marker position more granularFrieder Schrempf2019-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To be able to check and set bad block markers in the first and second page of a block independently of each other, we create separate flags for both cases. Previously NAND_BBM_SECONDPAGE meant, that both, the first and the second page were used. With this patch NAND_BBM_FIRSTPAGE stands for using the first page and NAND_BBM_SECONDPAGE for using the second page. This patch is only for preparation of subsequent changes and does not implement the logic to actually handle both flags separately.

However, relying on the dummy_controller is already deprecated. Switch over to the new controller/chip representation. The struct denali_nand_info has been split into denali_controller and denali_chip, to contain the controller data, per-chip data, respectively. One problem is, this commit changes the DT binding. So, as always, the backward compatibility must be taken into consideration. In the new binding, the controller node expects #address-cells = <1>; #size-cells = <0>; ... since the child nodes represent NAND chips. In the old binding, the controller node may have subnodes, but they are MTD partitions. The denali_dt_is_legacy_binding() exploits it to distinguish old/new platforms. Going forward, the old binding is only allowed for existing DT files. I updated the binding document.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Denali IP adopts the syndrome page layout (payload and ECC are interleaved). The *_page_raw() and *_oob() callbacks are complicated because they must hide the underlying layout used by the hardware, and always return contiguous in-band and out-of-band data. The Denali IP cannot reuse nand_{read,write}_page_raw_syndrome() in nand_base.c because its hardware ECC engine skips some of first bytes in OOB. That is why this driver implements specially-crafted *_page_raw() and *_oob() hooks. Currently, similar code is duplicated to reorganize the data layout. For example, denali_read_page_raw() and denali_write_page_raw() look almost the same. The complexity is partly due to the DMA transfer used for better performance of *_page_raw() accessors. On second thought, we do not need to care about their performance because MTD_OPS_RAW is rarely used. Let's focus on code cleanups rather than the performance. This commit removes the internal buffer for DMA, and factors out as much code as possible.
